DRILL PRESS

WIPO Patent Application WO/2009/030175

A1

A drill press has a base (1), a column (12) engaging with the base (1) and a main spindle box (13) engaging with the column (12). Wherein the main spindle box (13) comprises a power unit and a working head (32) driven by the power unit. The drill press further comprises a first worktable (151) and a second worktable (152), and a position quick changing device (14) is provided between these two worktables (151,152). Said position quick changing device (14) can alternatively adjust the first or the second worktable (151,152) to a working position quickly such that one of these two worktables (151,152) can be set as a supporting surface with workpieces supported thereon. One of these two worktables (151,152) is a V-shaped worktable (152) and the other is a conventional worktable (151). Thus, it is possible to choose the first or the second worktable (151,152) to be the workpiece supporting surface only through the position quick changing device (14) and it is not necessary for an operator to use a V-block during operation.
